Sound control apparatus, program, and control method

Abstract

A sound control apparatus includes a display unit and a controller. The display unit is configured to display an object on a screen. The controller is configured to control a volume of information on the object based on one of a position and area of the object on the screen.

1 . A sound control apparatus, comprising:
 a display unit configured to display an object on a screen; and   a controller configured to control a volume of information on the object based on one of a position and area of the object on the screen.   
     
     
         2 . The sound control apparatus according to  claim 1 ,
 wherein the controller controls a sound signal of a sound output unit such that the information on the object is heard from a direction corresponding to the position of the object on the screen.   
     
     
         3 . The sound control apparatus according to  claim 1 ,
 wherein the controller controls the volume of the information on the object based on a distance between a center position of the screen and a center position of the object.   
     
     
         4 . The sound control apparatus according to  claim 3 ,
 wherein the controller controls the volume of the information on the object such that the volume becomes larger as the distance between the center position of the screen and the center position of the object becomes smaller.   
     
     
         5 . The sound control apparatus according to  claim 1 ,
 wherein the controller controls the volume of the information on the object such that the volume becomes larger as the area of the object on the screen increases.   
     
     
         6 . The sound control apparatus according to  claim 1 ,
 wherein the controller controls the volume of the information on the object based on both the position and area of the object on the screen.   
     
     
         7 . The sound control apparatus according to  claim 1 , further comprising
 an input unit,   wherein the controller judges a selection operation of the object via the input unit and changes the volume of the information on the selected object according to the selection operation of the object.   
     
     
         8 . The sound control apparatus according to  claim 7 ,
 wherein the controller changes the volume of the information on the selected object such that the volume of the information on the selected object becomes larger.   
     
     
         9 . The sound control apparatus according to  claim 1 , further comprising
 an image pickup unit configured to pick up an image of a real object that actually exists in space,   wherein the controller causes the real object photographed by the image pickup unit to be displayed as the object on the screen and controls a volume of information on the real object based on one of a position and area of the real object on the screen.   
     
     
         10 . The sound control apparatus according to  claim 9 ,
 wherein the controller changes, when one of the position and area of the real object photographed by the image pickup unit on the screen is changed, the volume of the information on the real object according to the change of one of the position and area of the real object on the screen.   
     
     
         11 . The sound control apparatus according to  claim 1 ,
 wherein the controller causes a virtual object to be displayed as the object on the screen and controls a volume of information on the virtual object based on one of a position and area of the virtual object on the screen.   
     
     
         12 . The sound control apparatus according to  claim 11 ,
 wherein the controller changes one of the position and area of the virtual object on the screen and changes the volume of the information on the virtual object according to the change of one of the position and area of the virtual object on the screen.   
     
     
         13 . The sound control apparatus according to  claim 12 , further comprising
 a sensor configured to detect a movement of the sound control apparatus,   wherein the controller changes one of the position and area of the virtual object on the screen according to the movement of the sound control apparatus detected by the sensor.   
     
     
         14 . A program that causes a sound control apparatus to execute the steps of:
 displaying an object on a screen; and   controlling a volume of information on the object based on one of a position and area of the object on the screen.   
     
     
         15 . A control method, comprising:
 displaying an object on a screen; and   controlling a volume of information on the object based on one of a position and area of the object on the screen.
